Used as an intermediate in organic synthesis, particularly in cross-coupling reactions such as Suzuki and Heck reactions, to construct biaryl and heterobiaryl systems found in pharmaceuticals and functional materials. Its bromine functionality allows for selective metal-catalyzed substitutions, making it valuable in the development of organic semiconductors, fluorescent dyes, and bioactive molecules. The sulfone group enhances electron-withdrawing properties and stability, which can improve performance in optoelectronic applications and as a building block in medicinal chemistry.
